Since my parts arrived early yesterday and I had a window of opportunity I pulled the springs and did some experimenting and altering.
Rubber bump stops with the suspension fully compressed against the corner weight of the car. The rubber stops free length is 1.5" and it compressed .5".
Same scenario as above with 1.25" poly sump stop in place. So it appears to have gained .25" of free travel and similar compressed travel, though beyond sitting on it's own weight the poly should be firmer than the rubber but the zerk is still in jeopardy in a G-out.
Hotchkis bar link installed at supplied length (1-5/8" spacer) in compression.
Same scenario with 1" spacer.
Same scenario with .75" spacer.
Suspension in full drop with bar link adjusted finger tight which leaves the bar holding the suspension approx 1" short of full drop.
Sitting at estimated ride height.
Global West cast aluminum 3/8" spacers.
Sitting at ride height with spacers installed.
It went from .5" free travel to 1.25 free travel with spacers and poly bump stops. Not ideal but a big percentage gain. Fender height went from 23-7/8" to 24-5/8".
Hopefully I'll be able to button up all the loose ends tomorrow, get it on the ground and set the caster/camber/toe and take it for a short test drive, then recheck dimensions and safety inspect before taking it on a real shakedown drive weather permitting.
